Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a device for adding alkali to pure water in production. Background Technique

[0002] In the process of cigarette production, water treatment equipment is often required. The most commonly used water treatment consumable in water treatment equipment is to add a certain amount of alkali when producing pure water. The main functions of adding alkali are to adjust the pH value of water, remove carbonic acid in water, increase the conductivity of pure water, protect equipment and sterilize.

[0003] However, during the injection of soda ash liquid medicine, due to the relatively large specific gravity of the soda ash liquid medicine, it is easy to sink to the bottom of the container and not dissolve in the solution water, resulting in a layering phenomenon, failing to achieve the purpose and function of adding alkali. And each barrel of soda ash liquid medicine is about 25KG. Every time when adding alkali, it is necessary to manually lift the soda ash liquid medicine barrel and mix it into the container. This is not only time-consuming and laborious, but also the concentration of the soda ash liquid medicine is relatively high, and it is easy to splash onto people's skin and clothes, causing burns to the skin and corrosion to the clothes. Content of the Utility Model
